The motor frame limiter 2 is arranged at the upper end of the base 1 to fix the motor frame. The punching piece 6 punches the motor frame. The mounting assembly 5 provides multiple points for the installation of the punching piece 6, so that the installation position of the punching piece 6 can be changed arbitrarily. The telescopic mechanism 4 is a cylinder; the telescopic mechanism 4 pushes the mounting assembly 5 to move so that the punching piece 6 penetrates into the motor frame; the fixed end of the telescopic mechanism 4 is arranged on the fixed plate 3; the fixed plate 3 is arranged on the base 1. The punching piece 6 includes a driving mechanism 61; the driving mechanism 61 is a motor; the driving end of the driving mechanism 61 is connected to a knife housing 62; a plug-in slot 63 is provided at the side wall of the knife housing 62, and a tool 64 is connected to the other end. The mounting assembly 5 includes a mounting frame 51; a limiting member 52 for limiting the position of the blade housing 62 by engaging with the insertion slot 63; and a limiting member 2 53 for limiting the position of the driving mechanism 61 by clamping the driving mechanism 61 from both sides.

[0021] Further explanation, the motor frame limiter 2 includes a bottom plate 21 arranged on the base 1; a vertical plate 22 is arranged at one end of the bottom plate 21, and a square frame 23 is arranged at the other end; a telescopic mechanism 24 is arranged on the vertical plate 22; the telescopic mechanism 24 is a cylinder; the telescopic end of the telescopic mechanism 24 is connected to a limit plate 25; the limit plate 25 is arranged toward the square frame 23. The lower frame of the square frame 23 is higher than the top surface of the bottom plate 21. The motor frame is pushed by the telescopic mechanism 24, and the motor frame is limited between the square frame 23 and the limit plate 25, which can prevent the motor frame from shaking and affecting the punching accuracy when punching the motor frame.

[0022] Further explanation, the mounting frame 51 includes a mounting plate 1 511 and a mounting plate 2 512; the mounting plate 1 511 and the mounting plate 2 512 are connected by a connecting column 513; the mounting plate 2 512 is connected to the telescopic end of the telescopic mechanism 1 4; the mounting plate 1 511 is arranged between the mounting plate 2 512 and the frame 23. The limiting member 1 52 includes slots 521 evenly arranged on the mounting plate 1 511; the slot walls of the plurality of slots 521 are symmetrically provided with mounting slots 522; the plurality of mounting slots 522 are slidably connected with plug blocks 523; the plug blocks 523 are provided with an adjustment slope at one end facing the motor frame limiting member 2, and springs 1 524 are connected between the plug blocks 523 and the corresponding mounting slots 522. The plug blocks 523 are engaged with the plug-in slots 63 to limit the position of the blade housing 62, so as to prevent the punching member 6 from shaking during punching and affecting the punching accuracy.

[0023] Further explanation, the second limiting member 53 is evenly arranged in multiple groups on the second mounting plate 512, and is opposite to the slots 521 one by one; the second limiting member 53 includes a connecting plate 531 symmetrically arranged on the second mounting plate 512; the two connecting plates 531 are connected to the second spring 532 at the opposite ends; the two springs 532 are connected to the second clamping plate 533 at the opposite ends. The shape of the clamping plate 533 is an arc that fits the side wall of the driving mechanism 61. The driving mechanism 61 is clamped from both sides by the clamping plate 533, and the driving mechanism 61 is limited, so that the punching member 6 is limited as a whole, and the installation of the punching member 6 is further reinforced.

[0024] The limiting member 1 52 and the limiting member 2 53 cooperate to limit the punching member 6, which can improve the stability of the punching member 6 during punching and prevent the punching member 6 from shaking during punching, which affects the punching; on the other hand, it can make the installation of the punching member 6 faster and more convenient. The distribution of multiple limiting members 1 52 and limiting members 2 53 improves the flexibility of the installation of the punching member 6, so that the installation position of the punching member 6 can be changed arbitrarily, thereby adapting to different styles of motor frames and increasing the scope of application of the device.

[0025] Further, the lower ends of the first mounting plate 511 and the second mounting plate 512 are connected to a slider 514 ; the slider 514 is slidably disposed in a slide groove 515 provided at the upper end of the base 1 , so as to improve the stability of the mounting assembly 5 .

[0026] The working principle of the utility model is as follows: when punching, first place the motor frame on the bottom plate 21, then start the telescopic mechanism 24 to extend the limit plate 25, and limit the motor frame between the frame 23 and the limit plate 25. Then, according to the point where the motor frame needs to be punched, install the punching piece 6 in the corresponding slot 521. During installation, insert the punching piece 6 into the slot 521, so that the spring 1 524 pushes the plug block 523 to cooperate with the plug slot 63, and at the same time, the spring 2 532 will push the two clamping plates 533 to clamp the driving mechanism 61 from both sides, so as to fix the punching piece 6 as a whole, and prevent the punching piece 6 from shaking during punching, which will affect the punching. Finally, start the telescopic mechanism 1 4 to drive the installation component 5 to slide along the slide slot 515, and start the driving mechanism 61 to drive the knife housing 62 and the knife 64 to rotate, so that the knife 64 punches the motor frame.

[0027] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
